The message "conflicts:  6 shift/reduce" is just a warning; it shouldn't
prevent Bison from creating the output file.

That might occur if "y.tab.c" already existed before you ran Bison.

I tried both Bison 1.35 and Bison 1.875 on INN 2.4.1's parsedate.y;
they both worked for me.

Perhaps your copy of INN is broken somehow.  Can you please try
running the following commands, to get a fresh version of INN's
source?

        mkdir new
        cd new
        wget ftp://ftp.isc.org/isc/inn/inn-2.4.1.tar.gz
        gunzip <inn-2.4.1.tar.gz | tar xf -
        cd inn-2.4.1/lib
        bison -y parsedate.y
        ls -l y.tab.c
        bison --version

The output of the above commands looks like this on my host.
As you can see, it works for me with Bison 1.875.

$ mkdir new
$ cd new
$ wget ftp://ftp.isc.org/isc/inn/inn-2.4.1.tar.gz
